The optical fiber decoration device is characterized by having an LED light source consisting of a plurality of LED&#39;s which are arranged at an end of optical fiber for emitting one or more colors and partially superimposed, enabling synthesis of colors. In  FIG. 1 , the optical fiber decoration device (I) includes an LED light source unit ( 2 ) and an optical fiber ( 1   a ). The distance L between the LED light source ( 2 ) and the optical fiber is 5 to 100 mm. Red, blue, and green LED&#39;s are used to realize multiple colors. The optical fiber decoration device can be used for signboards, outdoor decorations, bus advertisement, indoor decorations, decorations in an aquarium, unit type Christmas trees, clothes, and the like.

FIELD OF INVENTION

This invention relates to optical fiber decoration devices. Specifically, it relates to optical fiber decoration devices using LED (light emitting diode) as a light source and decoration items using these devices. The light source can emit multiple colors, has a long lifetime and low power consumption, is very safe, and has a fantastic appearance.

BACKGROUND OF THE INVENTION

Recent years have seen the development of decoration items using lights, the light source being lamps or the combination of lamps and optical fiber, to decorate Christmas trees and advertising boards. For instance, in the case of general Christmas trees, the effect of the decoration has been achieved by means of blinking or continuously light colored bulbs that were mounted to branches and treetops of natural and artificial trees. In order to change the color, a technique was applied by inserting a colored translucent medium, such as the colored glass or colored cellophane, between a lamp of the light source and the light entrance of the optical fiber ends and letting the light pass through this translucent medium and illuminate an optical fiber.

The decoration item, like the above-mentioned, can be dangerous because fire can occur due to the heat of the lamp and the adaptor, since it uses a lamp with high power consumption. This results in not only a complex waterproof design but also a higher cost. When miniaturizing the item, it is difficult to use a battery and hence has poor portability. Lamp has faults such as a short lamp lifetime and high rate of generating defective goods due to the failure from accidents during transportation. Therefore, the optical fiber decoration device using lamps as a light source has the problem on restrictions of the usage and the place. On the other hand, when a large-scale decoration item is produced, for instance a Christmas tree, the length of optical fibers becomes long from the light source when a lamp is used as the light source. In this case, there is a problem that the brightness from the other end decreases because the attenuation of light occurs when passing through an optical fiber. When an electric decoration was attempted on clothes, the optical fiber decoration device using a lamp as the light source does not allow wearing for a long time as well as has a poor portability due to the heat.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In the following context, this invention will be explained more specifically with figures. FIG. 1 shows a cross-sectional diagram which the basics of the optical fiber decoration device of this invention. In FIG. 1, the optical fiber decoration device described in claim 1 of this invention is characterized by that multiple LEDs emitting at least monochromatic or polychromatic light are installed at the end of the optical fiber, and has a LED light source these which enable the color mixing by overlapping of some of these colors. The optical fiber decoration device I consists of a LED light source unit 2 and an optical fiber 1 a. In order for a LED light source unit 2 to emit light, it is necessary to connect a controller (refer to FIG. 5) to the LED. Thus, that the LED light source emits light means that not only a controller is used but also a controller is integrated with the LED light source.

The optical fiber 1 used for this invention is the one that the light passes through within fiber, light enters from one end of the optical fiber and is emitted from another end. The diameter of the optical fiber 1 is 0.4-0.5 mm, and 0.1-0.3 mm is preferable. The optical fiber bundle 1 a which bundled this optical fiber 1 consists of 10-30000 optical fibers 1. 100-30000 is preferable and 100-20000 is more preferable. Optical fiber is usually formed so that light may not leak from the perimeter wall. In this invention, optical fibers are constructed to allow light leaking from the perimeter wall at regular or irregular intervals. For example, a crack may be created in the perimeter wall to allow the light leakage from there. The crack may also be a point, a line, or a spiral line. The distance between the LED unit 2 and the optical fiber 1 a, being referred to as L, is 5-100 mm preferably. Since L changes with the kinds of the LEDs and the luminosity, it is desirable to determine the optimal distance using a simple test before it is used. As one example for the configuration to maintain the distance L and the connection between the LED unit 2 and optical fiber 1 a, an arrangement to maintain the distance L is desirable after one end 1 b of the optical fiber bundle is bonded to form a joint 4 using an adhesive.

Although the optical fiber decoration device I of this invention can be arranged one or more LEDs, it may be desirable to arrange three LEDs with different colors. The most desirable example is shown in FIG. 3. FIG. 3 shows a perspective diagram of the example of the mixing colors of red, blue, and green. In FIG. 3, the LED unit 2 is formed by containing three LEDs of red LED 2 c, blue LED 2 a, and green LED 2 b in the container 5. This unit 2 emits three primary colors, emits light in yellow 2 bc by red 2 c and green 2 b, emits light in bluish green (cyanogen) 2 ab by blue 2 a and green 2 b, and emits light in purplish red (magenta) 2 ac by red 2 c and blue 2 a. The way to emit light of three primary colors was explained in the example of this invention, without being limited to these, two or more different colors may be overlapped partially, thereby, countless mixtures of colors can be obtained. The illumination angle (θ) of a LED lamp used as a LED light source (hereafter called a lamp also) depends on the diameter of the LED lamp. For example, when the diameter of this lamp is larger than 2.5 mm, the desirable illumination angle (θ) is 10-50 degree. In this case, the interval of the multiple LED lamp of 0-15 mm is desirable. A few to multiple colors can be created by making the distance from the point of a LED lamp emitting light to the light entrance of an optical fiber larger than the intersection of illumination lights. Although in these examples, the light sources are fixed, when a LED light source is moved forward and backward, or it is moved while rotating, it can create countless colors by the motion (refer to FIG. 15 b) even if the distance of the illumination light is below an intersection.

When the diameter of a LED lamp, for example, is less than 2.5 mm, the illumination angle of 0-35 degree is desirable. The interval of multiple LED lamps is 0-15 mm, similar to the case that the diameter of the LED lamp mentioned above is over 2.5 mm, a few to multiple colors can be created by making the distance from the point of a LED lamp emitting light to the light entrance of an optical fiber larger than the intersection of illumination lights. Although the above examples are light sources that are fixed, when a LED light source is rotated, it can create countless colors by the motion even if the distance of the illumination light is below an intersection. Especially when a LED lamp is moved back and forth or rotated, that is, making a LED lamp move (such as up and down, left and right, slant, etc. with proper angles, back and forth motion, or regular and irregular rotation), one, a few to many colors can be created. In this invention, controls of blinking, 2-color control, 3-color control, etc. can be performed by combining an emitting control device with the optical fiber decoration device. Some arranged LED lamps can blink regularly or irregularly, and they can be made dark or bright by gradually weakening and strengthening the luminosity. The color from an optical fiber using such a LED light source can be varied. This control device is made by mechanical control, for example, a control rod is rotated by a motor and the electrical contact and non-contact. It is also controllable using electric elements.

The optical fiber decoration device described in the claim 2 of this invention is characterized by integration of the end of an optical fiber with the head of LED. FIG. 2 is a cross-sectional diagram showing the optical fiber decoration device. As shown in FIG. 2, integration of the optical fiber decoration device (refer to II) was formed by inserting and fixing a cylinder 5 into the head of a LED, and then inserting light entrance of optical fiber bundle 1 a in the upper part of a cylinder 5. Another variation is that the adhesion part 4 is formed by inserting a LED 2 into a cylinder 5 and bonding bundle 1 a of an optical fiber 1 with an adhesive. When the upper surface of the LED is round, bundle 1 a of an optical fiber 1 may be pasted along the circular side. For decoration, LED may be desired to emit monochromatic light, any three primary colors, as well as any colors by mixing two or more colors. Arbitrary colors can be arranged into the required part of the decoration by this composition.

Because the optical fiber decoration device described in the claim 3 of this invention is characterized by arranging a condenser lens between multiple LED light sources and the optical fiber, the luminosity of the LED light source, or the luminosity from LEDs to an optical fiber bundle, can be increased. FIG. 4 is a cross-sectional diagram showing the optical fiber decoration device with a condenser. In FIG. 4, the luminosity is increased by increasing the number of LEDs 2, and a lens 30 is inserted between the optical fiber bundle 1 a and the LED light source 2 to collect the LED illumination. The illumination is condensed into the light entrance 1 b of an optical fiber bundle 1 a with this lens 30. Consequently, the luminosity at the light entrance of an optical fiber increases, so the light emitted from the tip of an optical fiber becomes very bright. According to the kind of lens, the brightness can be adjusted by increasing the brightness of a LED light source, or changing the width and the illumination angle of the beam. As for lens, the change in light can be achieved by scattering light using a special lens, for example, a lens with facet-cut surfaces. In addition, the beam emitted from a LED lamp can be controlled by a lens, it can be set up so that LED lamps may blink or change colors by interlocking with one or more IC boards using the above-mentioned controller, and LED lamps can blink and change colors accompanying the sound and rhythm of music.

The optical fiber decoration device described in the claim 4 of this invention is characterized by that the luminosity of singular or multiple LEDs can be at least gradually changed. The optical fiber decoration device described in the claim 5 of this invention is characterized by that multiple colors can be created that is added colors to mix by independently changing individual luminosity of the multiply LEDs. In the invention described in the claim 4 and 5, the emitting color (mixed color) can be controlled by decreasing or increasing the luminosity of more than two kinds of LEDs, using the emitting control device to control LED luminosity. The decorative effect can be enhanced by blinking the LEDs. Blinking can be formed by the combination of one, two, three, or various colors in the case of many colors.

The optical fiber decoration device described in the claim 6 of this invention is characterized by controlling the LED luminosity with a microcomputer. Operations of changing luminosity and blinking using microcomputer technology can be carried out by the optical fiber decoration device, described in the above-mentioned claim 4 and 5. This control circuit can be carried out using either mechanical or electric methods, and can use well-known technologies in this technical field. To change the emitting color or the luminosity one can manually switch the optical fiber decoration device described in the claim 7 of this invention. In this case, to change the pattern of the luminosity one can change the luminescence control circuit with a manual switch, or change the software controlled by a microcomputer. For example, LEDs are arranged so that each color of the red, blue, and green LEDs may overlap partially. A switch is installed for these LEDs so that the desired color can be obtained by switch operation, switch on or switch off. If red LED is turned off, an overlapped color that is yellow color can be obtained by mixing lights from the blue and green LEDs.

The optical fiber decoration device, described in the claim 8 of this invention, can carry out switching according to the signal from a sensor by the manual switch described in the claim 7. The sensor used in this case is characterized by changing luminosity controlled by the detection of sound or light. For example, a sensor for detection of sound or light is installed in the optical fiber decoration device, and the luminescence pattern is controlled by a microcomputer program according to the signal detected by the sensor.

The optical fiber decoration device, described in the claim 8 of this invention, is characterized by using a unit integrated from the optical fiber decoration device with the LED power supply. In the optical fiber decoration device I in FIG. 1, the optical fiber decoration device I shown in FIG. 2, and the optical fiber decoration device in FIG. 4, controller 6, luminescence controller 8, and power supply 7 are connected in the optical fiber decoration device II as shown in the block chart in FIG. 5. Among these, controller 6 is sometimes built in and integrated with the optical fiber decoration device, and sometimes arranged separately with the optical fiber decoration device. Here, the controller 6 is used to control the emitting of the LED light source of the optical fiber decoration device. The luminescence controller 8 is used to control the luminosity after the event when the LED light source emits light. For example, it can be controlled by increasing and decreasing the luminosity or by blinking. Therefore, the integration of the optical fiber decoration device 1I with a power supply 7 naturally means the integration of a controller 6, a luminescence controller 8, and a power supply 7.

A power supply 7 is used as a LED power supply, such as a battery or a storage battery. It is desirable to integrate the optical fiber decoration device, the controller 6, the luminescence controller 8, and power supply 7 as a unit. For example, making them into a unit requires integration of an optical fiber, LED, a controller, a luminescence controller, and a power supply in a container or a case. Not to mention, a switch to supply to the optical fiber decoration device and cut the electric power, has been installed.

The optical fiber decoration device, described in the claim 10 of this invention, is characterized by using a power supply obtained from a solar cell as a power supply for LED. It is advantageous to use a solar cell as a power supply since a LED has little power consumption. When using a solar cell, it is desirable to charge a supplemental storage battery for a solar cell, and then use the storage battery as a direct power supply. FIG. 6 is a circuit diagram showing the example to use the solar cell for the power supply. In FIG. 6, the optical fiber decoration device II is connected with the storage battery 9 and the solar cell 10. In the optical fiber decoration device II, the electric power is supplied by storage battery 9, the storage battery 9 is supplied by a solar battery 10, which is charged in daytime.

At least a part of the optical fiber decoration device, described in the claim 1 of this invention, is waterproof. The waterproof method is to build a waterproofing structure by filling up and covering with resin to make the part watertight in LED light source. For example, the whole part of a LED light source, except the optical fiber in an optical fiber decoration device, is made waterproofing (that is, the whole LED light source) by covering with resin. FIG. 7 is a cross-sectional diagram showing an example of the waterproofing structure of the optical fiber decoration device of this invention. FIG. 7 shows a cross-sectional diagram of waterproofing of the optical fiber decoration device shown in FIGS. 1 to 4. In FIG. 7, the lower part of the LED light source, except the optical fiber of optical fiber decoration device, is inserted in a prevention connector 11, and a code 12 extended from this connector 11 is connected to the waterproofing case 13. The waterproofing case 13 contains the luminescence controller 8 and the power supply 7. When a power supply 7 uses a battery, in order to exchange a battery, a lid is installed in a waterproofing case and the lid can be opened for the battery exchange. In this case, not to mention, the opening and shutting part of the lid is made watertight.

The optical fiber decoration device, described in the claim 12 of this invention, is a decoration device characterized by using the optical fiber decoration device described in either one from the above-mentioned claim 1 to 11. Here, a Christmas tree is given as an example for explanation. FIG. 8 is a side view showing the Christmas tree decorated by the optical fiber decoration device. In FIG. 8, Christmas tree 111 uses a bowl as a support part, the plinth 17 of this bowl has an artificial trunk 14 for a Christmas tree, and this tree has the branch 15 and the leaf 16. There is a cavity 14 a inside the trunk 14 and the branches 15. The optical fiber bundles are distributed to this cavity 14 a according to the number of branches 15, the tip of an optical fiber is exposed at the branch tip along each branch 15. The exposed tip may be expanded into a flower shape 19 of the morning-glory. On the other hand, a plinth 17 contains the LED light source 2, the luminescence controller 8, and the power supply 7. At the upper part of the LED light source 2, a bundle of optical fiber (1000 beams/bundle) 18 a is installed at the position of L=10 mm from the light source. The tip of this optical fiber bundle 18 a is distributed into a proper number along each branch, and is further divided into 40-50 beams at the tip of a branch.

FIG. 9 is a cross-sectional diagram showing another example of a Christmas tree of this invention. In FIG. 9, the Christmas tree IV consists of a trunk 14 for Christmas trees in the plinth 17 of a bowl, and this tree has branches 15 and leaves 16. There is a cavity 14 a inside the trunk 14 and branches 15. In the cavity 14 a, lead lines 20 are arranged from a plinth 17 to each branch 15, the tip of each branch 15. The end of the lead has a joint, where the optical fiber decoration device II is mounted and connected. The optical fiber decoration device II shown in FIG. 10 a can be either types shown in FIG. 1 or FIG. 2, but the type shown in FIG. 1 is preferable. In FIG. 10 a, the optical fiber decoration device II, consisting of a plug socket 21, a LED light source 2, and an optical fiber bundle 1 a, has two kinds of modes. One type shown in FIG. 10 b is that LED 2 has a cylinder 24 and the LED 2 and the plug socket 21 are integrated, and the optical fiber bundle 1 a bundled by the annular cylinder 23 is embedded. Another type shown in FIG. 10 c is that optical fiber decoration devices I or II are inserted into a plug socket 21. The latter is preferable.

The optical fiber decoration device of this invention is not limited to the types shown in FIG. 1, FIG. 2, or FIG. 4 as mentioned above. As one example, the one marked by sign 25 in FIG. 9 is often enumerated as the type to decorate a house. FIG. 11 shows an enlarged cross-sectional view of the mark 25 in FIG. 9.

In this invention, executed configurations of the optical fiber decoration device are explained in FIG. 8 and FIG. 9, it can be used for combination of the executed configurations of the optical fiber decoration device for a Christmas tree. FIG. 12 is a cross-sectional diagram showing another executed configuration of this invention. In FIG. 12, a plug socket 21 is installed at the branch tip 26, and an optical fiber decoration device IV is inserted in this plug socket 21. The optical fiber decoration device IV is designed similar to the one shown in FIG. 8. In the optical fiber decoration device IV, the main body consisting of the cylinder has the LED light source 2, a gap, and the end of the optical fiber. The optical fiber bundle 1 a is formed freely without fixing each optical fiber 1. At each branch tip 15, the tip of the optical fiber bundle 1 a is usually arranged to spread in flower shape 19 of the morning-glory. By arranging the luminescence controller 8 in a plinth 17 and connecting with each optical fiber decoration device IV by a lead line, various optical decoration patterns can be created according to the types of software. A Christmas tree with fantastic light can be obtained by properly mixing the lights from the LED light source in a plinth 17 with the light from the optical fiber decoration device IV installed in each branch and leaf.

The executed configuration is a decoration item of the Christmas tree on the market. For example, in the Christmas tree miniature bulbs with different colors are installed on the trunk, branches, leaves of a tree and a power supply is applied from the power supply (AC power) in a plinth with the lead line. The optical fiber decoration device II with built-in power supply shown in FIG. 2 is set up in the part of trunk, branches, and leaves. As a result, the effect of miniature bulbs and the effect of the optical fiber decoration device are expressed mutually, and a more fantastic Christmas tree is obtained. In a Christmas tree explained as an example so far, the LED light source 2 is contained in the plinth 17 in FIG. 8, while LED 2 is installed at branching areas as shown in FIGS. 9 and 12. In addition, an IC circuit and a LED light source can be arranged at the central part or side part of a Christmas tree, so that it can shorten the distance that a LED light source passes through an optical fiber and light emitting out from an optical fiber tip can be made brighter. The invention of the claim 14 of this invention concerns the decoration item characterized by that LED light source devices consisting of a LED light source and an IC board are arranged somewhere on the decoration item, and a light entrance face of the optical fiber is arranged in this LED light source device.

The illumination angle of these LEDs is θ, different colors are emitted onto the optical fibers (not shown in the figure, refer to FIG. 1) arranged at the upper part with the illumination angle, O. In this case, for instance, mixed colors can be obtained by partially mixing light 2 a, 2 b, and 2 c (emitted from LEDs 2 a, 2 b, and 2 c, respectively) with light 2 d, 2 e, and 2 f (emitted from LEDs 2 a, 2 b, and 2 c, respectively, in the second layer). Specifically, the mixed colors 2 ad, 2 cf, 2 af, 2 bd, 2 bf, 2 abd, 2 abe, 2 abf, and . . . can be obtained. Similar to the upper surface, mixed colors of each light can be also obtained in the back of the IC board 28. In this example, it is explained that LEDs on an IC board were arranged in two layers, it is clear that only the first layer may be arranged to use (refer to FIG. 15 d). FIG. 15 is a simple perspective diagram showing the executed configuration of the LED light source device 33. There are various kinds of configurations of the LED light source device 33. In FIG. 15 d, the LED unit 2 is formed which contains three illumination LEDs, red 2 c, blue 2 a, and green 2 b, in a container 5 in a cylinder 22. This unit 2 emits lights of three primary colors. Lights in red 2 c and green 2 b produce a color of yellow 2 bc, lights in blue 2 a and green 2 b produce a color of blue green 2 ab (cyanogen), and lights in red 2 c and blue 2 a produce a color of purple (magenta) 2 ac. In FIG. 15 b, LEDs 2 a, 2 b, and 2 c are properly arranged on the surface of an IC board 28, while LEDs 2 a, 2 b, and 2 c are properly arranged at the back. The color mixed from each light, emitting from these LEDs, is introduced into the optical fiber. In this example, it is shown that LEDs are arranged on both sides of the IC board 28. In place of this, two IC boards 28 can be fixed on the back of each other by fixing implements, for example, a screw and a bolt (not shown in the figure). In FIG. 15 c, LED2 a, 2 b, and 2 c are arranged on an IC board 28 a, while LED2 a, 2 b, and 2 c (different colors emitting from these LEDs are acceptable) are arranged on IC board 28 b consisting of transparent board above the IC board 28 a. In this case, the IC board 28 a and the IC board 28 b can be fixed, turned, or moved or rotated. These LED light source devices 33 is combined with the above-mentioned controller, light can be changed to various colors periodically by the rotation and cyclic movement of transparent board 31. In other words, the color mixture created from each color in these operations, and the fantastic world is produced. In FIG. 15 d, LED2 a, 2 b, and 2 c are arranged on IC board 28 a.

FIG. 16 is a cross-sectional diagram showing the LED light source device arranged in a Christmas tree. FIG. 16 a is a cross-sectional diagram showing the device build in the trunk of the Christmas tree. FIG. 16 b is a cross-sectional diagram showing multiple LED light source devices that are built in. In FIG. 16 a, as for LED light source device 33, a LED light source device 33 w was built in the trunk (the center part of a Christmas tree VI), the top and bottom part of the LED light source device 33 is arranged with the upper and lower parts of a Christmas tree, respectively. Concerning the upper and lower parts of these Christmas trees, trunk contains the optical fiber built-in parts 36 a and 36 b, and branch consists of side part 37 in the cylinder (not limited to a cylinder, it can be a triangle, a square, and a hexagon), a part of the optical fiber 1 contained in this cylinder is exposed through the side part 37 and. Moreover, the support stick 34 is set up as a stand. To support the Christmas tree, the support stick 34 is installed on a support part 35. The support part 35 can be installed by a proper method. In this example, it is not necessary to install a plinth since it is not necessary to employ the LED light source equipment 33 in a plinth while supporting a Christmas tree by the support part 35. Since the LED light source device 33 is not contained in a plinth from this structure, it is not necessary to install a conventional plinth, that is, a plinth is not needed. Thus, it enables us to make a Christmas tree with the advantages of low cost, waterproof, energy saving, and while being safe. Since the LED light source device 33 can be arranged in a suitable place on a Christmas tree VI as shown in this example, an outstanding effect is achieved: it is extremely simple, economical, and easy to construct a huge Christmas tree, only by increasing the number of these LED light source devices 33.

In FIG. 16 c, the LED light source device 33 is horizontally installed near the center part of Christmas tree VI, and is closely joined or connected with the optical fiber 1. The trunk of a Christmas tree VI has the support stick 34 in the lower part, and also has a support part 35 to get further standing stability of a Christmas tree. Since the LED light source device 33 was horizontally installed near the central part of Christmas tree VI, light can be distributed from optical fibers 1 employed on both VIa(s) and VIb(s) of Christmas tree VI. Because of the length of optical fibers can be shortened and a plinth is not required, this enables us to reduce the overall weight by installing a support stick 34 in a stripe part 35 for easy carrying and the reduction in cost. In FIG. 16 c, the LED light source device 33 is arranged in the center part of Christmas tree VI and the side part of a trunk, instead of arranged in the plinth. Therefore, it is not necessary to install a plinth, sticking foot in the ground, that is, a support stick instead of plinth, is installed as described later. The support part 35 can also be installed to get further stability. Since the LED light source device 33 is not contained in a plinth, plinth can be made much smaller than a conventional plinth, or a plinth is not required. Thus, a Christmas tree can be produced with advantages of low cost, waterproof, energy saving, and while being safe. Since the LED light source device 33 can be arranged in the suitable place on a Christmas tree VI as shown in this example, an outstanding effect is achieved: it is extremely simple, economical, and easy to construct a huge Christmas tree, only by increasing the number of these LED light source devices 33. When a Christmas tree VI is comparatively small, LED light source device 33 can be installed in the plinth instead of installation in a Christmas tree. In this case, the plinth itself can be comparatively small, so that it can reduce the material cost and easy carrying.

The lights emitting from these LED light source devices 33 a, 33 b, and 33 c pass through the optical fiber 1 arranged in the predetermined place and is exposed from the tip of the optical fiber 1. In cylinders 36 a, 36 b, and 36 c, branches contains side parts 37, a part of optical fiber 1 contained in these cylinders is exposed through this side part 37. This Christmas tree VII is constituted in combination of blocks VIIa, VIb, and VIc successively. Since the LED light source device 33 is not necessarily stored in a plinth in this structure, plinth can be made much smaller than a conventional plinth or a plinth is not required. Thus, a Christmas tree can be produced with advantages of low cost, waterproof, energy saving and while being safe. Since the LED light source device 33 can be arranged in the suitable place on a Christmas tree VII as shown in this example, an outstanding effect is achieved: it is extremely simple, economical, and easy to construct a huge Christmas tree, only by increasing the number of these LED light source devices 33.

As a result, it is extremely easily to drive it to the ground, and a Christmas tree VIII can be supported with good stability. In this case, the trunk of Christmas tree VIII can either be embedded and connected directly to a metal fitting 34 a, or be embedded in a lent support stick. In the example of FIG. 18 b, a support part 35 can be installed on a metal fitting 34 a which is attached on a support stick 34 of Christmas tree VIII.
